Benefits of technology

The contaminant reducing device described in this patent can oxidize nitrogen monoxide and neutralize acidified cleaning water using a purification process that generates hydrogen from seawater. This can reduce installation and maintenance costs and increase space utilization in a ship. The generated hydrogen can also be used as a driving source for the purification unit and other devices, making the system more efficient. The device also improves oxidation efficiency by removing fine dust before oxidizing sulfur oxides and nitrogen oxides, and reduces contaminants in the exhaust gas through a wet scrubber. Additionally, the device prevents the reduction of oxidized sulfur oxides and nitrogen oxides by injecting a liquid catalyst and passing the exhaust gas through the wet scrubber, resulting in improved reduction efficiency and significant reduction of contaminants in the exhaust gas.

Problems solved by technology

Here, exhaust gas generated in the fuel combustion process contains harmful substances such as sulfur oxides (SOx), nitrogen oxides (NOx), and fine dust (PM).
Thus, if the exhaust gas is discharged as it is, it can cause air pollution.

first embodiment

[0033]Hereinafter, a contaminant reducing device according to the inventive concept will be described in detail with reference to FIGS. 1 through 5.

[0034]A contaminant reducing device according to an embodiment of the inventive concept a device capable of reducing the concentration of various contaminants (nitrogen oxides, sulfur oxides, dust, etc.) contained exhaust gas to discharge that meets exhaust standards while treating cleaning water used to reduce the concentration of exhaust gas. The contaminant reducing device is mainly mounted on a ship to remove contaminants of exhaust gas generated in the ship.

[0035]The contaminant reducing device oxidizes nitrogen monoxide contained in exhaust gas with an oxidizing agent generated in a purification unit for electrolyzing seawater and, at the same time, neutralizes acidified cleaning water with a neutralizing agent generated in the same purification unit, thereby reducing the system installation and maintenance cost and increasing the ...

second embodiment

[0083]Hereinafter, a contaminant reducing device according to the inventive concept will be described in detail with reference to FIGS. 6 through 11.

[0084]The contaminant reducing device can improve oxidation efficiency by removing fine dust before oxidizing sulfur oxides and nitrogen oxides. In addition, since oxidized exhaust gas is double purified as it passes through a wet scrubber, contaminants in the exhaust gas can be significantly reduced. Also, the oxidized exhaust gas is dissolved in cleaning water to produce strong acid that can kill microorganisms in the cleaning water.

[0085]The contaminant reducing device will now be described in detail with reference to FIGS. 6 and 7.

[0086]FIG. 6 is a schematic view of a contaminant reducing device according to a second embodiment of the inventive concept. FIG. 7 is a cross-sectional view of an example of a pretreatment unit of FIG. 6.

third embodiment

[0130]Hereinafter, a contaminant reducing device according to the inventive concept will be described in detail with reference to FIGS. 12 through 14.

[0131]The contaminant reducing device according to the third embodiment of the inventive concept can prevent the reduction of oxidized sulfur oxides and nitrogen oxides by injecting a liquid catalyst into the oxidized sulfur oxides and nitrogen oxides before a gas-liquid contact. Therefore, the reduction effect of the sulfur oxides and the nitrogen oxides can be improved. In addition, since the oxidized exhaust gas is double purified as it passes through a wet scrubber, contaminants in the exhaust gas can be significantly reduced.

[0132]FIG. 12 is a schematic view of a contaminant reducing device according to a third embodiment of the inventive concept.

[0133]The contaminant reducing device 400 according to the inventive concept includes an exhaust gas tube 410, a cleaning water supply tube 420, a scrubber 430, an oxidation unit 440, a l...

Abstract

A contaminant reducing device is provided. The contaminant reducing device comprises: an exhaust gas tube for supplying exhaust gas from a combustion engine; a cleaning water supply tube for supplying cleaning water; a scrubber for spraying cleaning water, which is supplied through the cleaning water supply tube, to exhaust gas supplied through the exhaust gas tube; an oxidation unit connected to the exhaust gas tube so as to oxidize the exhaust gas by discharging electricity, emitting ultraviolent rays, or spraying an oxidizer; and a cleaning water discharge tube for discharging cleaning water from inside the scrubber.
